Okay fellow Make-Gyvers, what do you get when you cross a peripheral power cable jumper, a paperclip, springs, and some 3D-printed housings? DIY test lead clips.
Test clips are easily acquired, but where’s the fun in that? [notionSuday] started by removing the lead connectors from the jumper, soldering them to stripped lengths of paperclip, bent tabs off the connectors to act as stoppers, and slid springs over top. Four quick prints for the housings later, the paperclip assembly fit right inside, the tips bent and clipped to work as the makeshift clamp. Once slipped onto the ends of their multimeter probes, they worked like a charm.
In the video you also get a glimpse of a battery holder [notionSunday] made using a 3D printer and some more paperclips. Take note — if you don’t have a cache of paperclips in your workspace, you may be missing out on critical hacking materiel.
If you can never have too many testing devices, this impressive LED tester will tell you the needed resistor value to make sorting through that pile of LEDs you have collecting dust that much easier.
